@rustbot modify labels: rollup

Extends the change from rust-lang#139653, which was on expressions, to literals. Fixes rust-lang#140098.

Includes the following changes: * Provide `abort` on AVR [1] [1]: rust-lang/compiler-builtins#830

…pes, r=fee1-dead,traviscross make abi_unsupported_vector_types a hard error Fixes rust-lang#116558 by completing the transition; see that issue for context. The lint was introduced with Rust 1.84 and this has been shown in cargo's future breakage reports since Rust 1.85, released 6 weeks ago, and so far we got 0 complaints by users. There's not even a backlink on the tracking issue. We did a [crater run](rust-lang#127731 (comment)) when the lint was originally added and found no breakage. So I don't think we need another crater run now, but I can do one if the team prefers that. rust-lang#131800 is done, so for most current targets (in particular, all tier 1 and tier 2 targets) we have the information to implement this check (modulo the targets where we don't properly support SIMD vectors yet, see the sub-issues of rust-lang#116558). If a new target gets added in the future, it will default to reject all SIMD vector types until proper information is added, which is the default we want. This will need approval by for `@rust-lang/lang.` Cc `@workingjubilee` `@veluca93` try-job: test-various

…boet Use posix_spawn on cygwin r? `@joboet` Depends on: - [x] rust-lang/libc#4387 - [x] rust-lang#140081

handle function alignment in miri tracking issue: rust-lang#82232 Fixes rust-lang/miri#4282 The `#[repr(align(N))]` attribute on functions was ignored when using miri. For such a function, its address should be a multiple of `N`. There is some further discussion in the thread [#t-compiler/const-eval > function address alignment](https://rust-lang.zulipchat.com/#narrow/channel/146212-t-compiler.2Fconst-eval/topic/function.20address.20alignment) on how `dyn Fn` should be handled. The behavior there appears to be consistent between miri and nightly, though both may be incorrect. In any case, that can be resolved separately.
